The use of serial testing in evaluating the need for comprehensive neuropsychological testing of adults

The aim of this study was to develop brief neuropsychological testing procedures that would identify adults (aged 15 and older) who need comprehensive neuropsychological evaluation. The tests used for screening were selected to (1) initially provide a broad catchment procedure followed by (2) a more diversified basis for prediction. The total time required to administer the screening measures is about 45 minutes. The criterion for the need for comprehensive testing was based on the General Neuropsychological Deficit Scale (GNDS), which summarizes 42 variables derived from the complete Halstead-Reitan Battery. The results indicated that the brief testing battery permitted accurate identification of persons who showed neuropsychological impairment based on comprehensive testing. Cutoff points were determined and guidelines were provided for use of the brief testing results.
